Hey fellow Final Fantasy VII fans! When it comes to materia management, I recommend focusing on leveling up your most important materia like Elemental, Magnify, and HP Up. For mission walkthroughs, make sure to steal from every boss to get rare items and always have a diverse party to handle different situations. In terms of character development, don’t neglect anyone – each character has unique strengths that can be maximized with the right materia combinations. Happy gaming!
